Colorless

A gray Earth where humans were changed into malformed creatures. The first episode of an action series begins with the protagonist trying to find a lost world using a peculiar-looking pistol.

The planet’s hues disappeared due to a massive solar flare. Deformed humans are becoming less in number. The power concealed in “color” and one “girl” holds the key to restoring the ancient world. While conducting research and defending a young woman named Chie, Avidia, who is aware that the few remaining colors in the world have a vast power, uses the colors to increase his own power and engages in combat with the Cult.
